Start from the day image
A finished daytime render keeps materials consistent; a model view works when you describe the materials too.

Before you start
Prepare your daytime render or model view
Dusk images are some of the most persuasive in a presentation, and some of the slowest to light by hand. Start from a daytime render or model view and ask RenderChat for the evening version: blue sky, glowing interiors, street lights.
Decide what glows
List the light sources that matter: every window, only the ground floor, facade uplights, a lit canopy.
Pick the hour
Blue hour keeps detail in the sky and building; full night is moodier but hides more.

Example briefs
Day to night briefs to start from
Copy a brief, paste it into RenderChat with your daytime render or model view, and change the materials and mood to match your project.
Turn this into a blue-hour render. Keep the building, materials and camera. Deep blue sky with a faint glow at the horizon, warm 2700 K light in all windows, soft facade uplights, wet pavement reflecting the lights, a few people at the entrance.
Same scene at night. Dark sky, interiors fully lit, warm path lights in the garden, the pool lit from inside, no people.
